[0054] With the continuous development of the automotive industry in recent years, the pursuit of automotive styling has become increasingly diverse. The vehicle manufacturer improves the diversity of the overall front styling and enhances the aerodynamic performance by placing the intake grille blades in the front. In the existing above-mentioned solutions, a linkage mechanism is often arranged between multiple blades, and a single one of the blades is driven to rotate by a driving motor, and then all the blades are driven to rotate synchronously. However, the above structure requires that all the blades rotate in unison.

[0055] The main purpose of the present utility model is to propose a blade structure, an intake grille module, a vehicle front end assembly and a vehicle, aiming to provide a solution that can meet the inconsistent rotation paces of the blades to satisfy the differential opening of the blades. However, in the above-mentioned solution, how to limit the rotation stroke of the blades is an urgent problem to be solved.

[0056] Please refer to Figures 1 to 2 , the present utility model also proposes an intake grille module 100. A blade driving part 30 is arranged in the intake grille module 100. The driving motor 20 drives the blade driving part 30 to move, and then drives the rotation of the blade structure 40, thereby realizing the opening and closing of the grille holes of the grille frame 10.

[0057] The present utility model proposes a blade structure 40. Please refer to Figures 3 to 8 , the blade structure 40 includes a blade body 1, two rotating shafts 2, a driving shaft 3 and a stop limiting part 4.

[0058] The blade body 1 has a driving end and a connecting end in its length direction.

[0059] The two rotating shafts 2 are coaxially arranged and are respectively arranged at the driving end and the connecting end. At least one of the two rotating shafts 2 is set as a limiting rotating shaft 2.

[0060] The driving shaft 3 is arranged at the driving end and is arranged non-coaxially with the rotating shaft 2.

[0061] The stop limiting part 4 is arranged on the limiting rotating shaft 2 and / or the blade body 1.

[0062] In the technical solution of the present utility model, the two rotating shafts 2 are coaxially arranged, and the rotation axis of the blade body 1 is in the axial direction of the rotating shaft 2. By driving the rotation of the driving shaft 3, the blade body 1 can rotate quickly. By arranging the stop limiting part 4, the blade body 1 can be well limited at a preset position during the rotation process, realizing the precise control of the blade body 1 to open the grille opening 101, making the matching state of the opening and closing of the blade structure 40 better, and increasing the stability of air intake.

[0063] It should be noted that the drive shaft 3 is used to drive and connect the blade drive part 30; the stop and limit part 4 is used to limit and abut against the grille frame 10 to limit the rotation stroke of the blade body 1.

[0064] It can be understood that in the technical solution of the present utility model, the two rotating shafts 2 are arranged at both ends of the blade body 1 in the length direction, the blade body 1 is rotatably arranged along the axes of the two rotating shafts 2, and the drive shaft 3 is arranged coaxially with the two rotating shafts 2, that is, two shafts are arranged at the drive end of the blade body 1, one of which is used as the support point for rotation and the other is used as the connection point for drive. Such an arrangement can simplify the arrangement of the rotating shaft 2. Compared with the way of arranging the rotating shaft 2 and the drive shaft 3 as one shaft, the structure is simple.

[0065] For the limiting rotating shaft 2, it can be any one of the rotating shafts 2. For example, the rotating shaft 2 arranged adjacent to the blade drive part 30 can be set as the limiting rotating shaft 2; or the rotating shaft 2 far from the blade drive part 30 can be set as the limiting rotating shaft 2; of course, in some embodiments, both of the two rotating shafts 2 can also be set as the limiting rotating shaft 2.

[0066] The stop and limit part 4 is arranged on the blade structure 40. The stop and limit part 4 can be arranged on the limiting rotating shaft 2 or on the blade body 1; of course, in some embodiments, it can also be arranged on both the limiting rotating shaft 2 and the blade body 1 at the same time.

[0067] The stop and limit part 4 is used to limit the rotation stroke of the blade body 1. During the rotation of the blade body 1, the blade body 1 abuts against the grille frame 10 for limiting.

[0068] In some embodiments, please refer to Figures 3 to 5 , the stop and limit part 4 includes a stop rib 41 arranged on the limiting rotating shaft 2. The stop rib 41 extends along the circumferential direction of the limiting rotating shaft 2 to form two first stop surfaces on the circumferential direction of the limiting rotating shaft 2.

[0069] The two first stop surfaces are used to alternately abut against the grille frame 10 during the rotation stroke of the blade body 1. Such an arrangement limits the rotation of the rotating shaft 2, and thus limits the rotation of the blade body 1. The shape of the stop rib 41 can be finely set, and then the rotation stroke of the blade body 1 can be directly defined, improving the stability of the rotation of the blade body 1.

[0070] It should be noted that the central angle of the stop rib 41 corresponding to the limit rotation shaft 2 can be angular values such as 10°, 15°, 20°, 30°, 40°, 50°, etc., and the central angle of the mating part provided on the grille frame 10 corresponding to the limit rotation shaft 2 is greater than the central angle of the stop rib 41 corresponding to the limit rotation shaft 2. For example, it can be angular values such as 15°, 20°, 30°, 40°, 50°, 60°, etc.; the difference between the two central angles is the rotation stroke of the limit rotation shaft 2.

[0071] On the rotation stroke of the limit rotation shaft 2, the two first stop surfaces alternately abut against the grille frame 10. For example, the limit rotation shaft 2 has two rotation limit positions. At one of the rotation limit positions, one of the stop surfaces abuts against a mating part provided on the grille frame 10; at the other rotation limit position, the other stop surface abuts against another mating part provided on the grille frame 10.

[0072] The stop rib 41 is integrally formed on the rotation shaft 2, that is, when the blade body 1 is formed, the rotation shaft 2 and the stop rib 41 are integrally formed. The structure is simple, and the rotation stability of the blade body 1 is better.

[0073] In addition, multiple stop ribs 41 can be provided and are spaced along the axial direction of the rotation shaft 2. By providing multiple stop ribs 41, multiple abutting contact points can be formed during stop abutment, and at the rotation limit position, the anti-rotation effect of the blade body 1 will be better.

[0074] In some embodiments, please refer to Figure 3 、 Figure 6 and Figure 7 , the stop and limit part 4 includes a limit rib plate 42. The side end of the limit rib plate 42 is connected to the end of the driving end and / or the connecting end of the blade body 1. The rib plate includes a first rib plate section 421 and a second rib plate section 422 arranged at an angle.

[0075] The first rib plate section 421 and the second rib plate section 422 are used to alternately limit and abut against the grille frame 10 during the rotation stroke of the blade body 1.

[0076] The limit rib plate 42 is arranged at the side end of the blade body 1 to limit the rotation of the blade body 1. Such an arrangement can simplify the setting of the rotation shaft 2.

[0077] When the limiting rib plate 42 is in limiting abutment with the grille frame 10, the side surface in the thickness direction of the limiting rib plate 42 is used to abut against the mating part provided on the grille frame 10, and the abutting area is large, which can well realize the rotation of the blade body 1 to the corresponding rotation limit position of the rotor.

[0078] The limiting rib plate 42 can be integrally formed with the blade body 1. For example, the blade body 1 and the limiting rib plate 42 are integrally injection molded.

[0079] In some embodiments, the first rib plate section 421 and the second rib plate section 422 can be formed by bending a single plate or by butt-jointing two plates. An included angle needs to be formed between the first rib plate section 421 and the second rib plate section 422 to correspondingly limit and abut against the mating part provided on the grille frame 10 at different rotation limit positions of the blade body 1 alternately.

[0080] Of course, the included angle between the first rib plate section 421 and the second rib plate section 422 and the position of the mating part provided on the grille frame 10 jointly determine the rotation stroke of the blade body 1.

[0081] In some embodiments, a reinforcing rib plate is provided between the blade body 1 and the limiting rib plate 42 to make the structural strength of the connection between the limiting rib plate 42 and the blade body 1 better.

[0082] The present utility model further provides an intake grille module 100, which includes a grille frame 10, a blade structure 40, a driving motor 20 and a blade driving part 30. The grille frame 10 is formed with a grille opening 101 extending in the front-rear direction. Two rotating shafts 2 of the blade structure 40 are rotatably installed at the edge of the grille opening 101 along the axis extending in the left-right direction. The housing of the driving motor 20 is connected to the grille frame 10. One end of the blade driving part 30 is drivingly connected to the output shaft of the driving motor 20, and the other end is drivingly connected to the driving shaft 3 of the blade structure 40. The specific structure of the blade structure 40 refers to the above embodiments. Since the intake grille module 100 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated herein one by one.

[0083] For the blade structure 40, to mount the blade structure 40 onto one of the grille frames 10, for the two rotating shafts 2, if the same mounting method is adopted, such as the shaft-hole mating method, interference mounting of the rotating shafts 2 needs to be achieved, that is, before or during the mounting, the two rotating shafts 2 are deformed to reduce the axial spacing, so as to achieve the mounting of the two rotating shafts 2.

[0084] In some embodiments, the two rotating shafts 2 can adopt different mounting methods. For example, one is the plugging method using shaft-hole mating, and the other is the radial crimping method. In this way, deformation of the rotating shafts 2 is not required to achieve the mounting, the mounting is more convenient, and the structure will not suffer fatigue damage due to deformation.

[0085] Specifically, please refer to Figure 4 , an accommodation groove 102 is provided on the grille frame 10, the notch of the accommodation groove 102 faces backward, and one of the rotating shafts 2 is rotatably mounted in the accommodation groove 102;

[0086] The intake grille module 100 further includes a pressing body 50, the pressing body 50 is arranged at the notch of the accommodation groove 102 to limit the rotating shaft 2 in the accommodation groove 102. With such a setting, the rotating shaft 2 can be easily rotatably mounted in the grille frame 10, and the assembly of the blade structure 40 and the grille frame 10 can be quickly achieved.

[0087] It should be noted that the shape of the pressing body 50 can also be set to have a similar groove structure. In this way, when the pressing body 50 and the accommodation groove 102 cooperate, they can jointly limit the rotating shaft 2 in the radial direction, reduce the radial runout of the rotating shaft 2, and improve the stability of the movement of the blade structure 40.

[0088] The mounting method of the pressing body 50 and the grille frame 10 is not limited, and it can be a threaded connection or a snap connection or other connection methods.

[0089] In the embodiment where the rotating shaft 2 arranged in the mounting groove is a limiting rotating shaft 2, please refer to Figures 3 to 5 , the stop limiting portion 4 includes a stop rib 41 provided on the limiting rotating shaft 2, the stop rib 41 avoids the pressing body 50, and is used to alternately abut and limit against the edge of the notch of the accommodation groove 102 during the rotation stroke of the blade main body 1. That is, the stop rib 41 only needs to abut against the edge of the notch of the accommodation groove 102, and no additional matching structure needs to be provided, and the structure is set more simply.

[0090] It should be noted that the placement groove 102 can be set to be relatively long, and the width of the pressing body 50 can be set to be relatively short. The avoidance of the stop rib 41 from the pressing body 50 can be understood as the stop rib 41 being beside the pressing body 50, that is, the stop rib 41 and the pressing body 50 correspond to different groove segments of the placement groove 102.

[0091] In the embodiment where two stop ribs 41 are provided on the limit rotation shaft 2, the pressing body 50 is located between the two stop ribs 41.

[0092] In some embodiments, two blade structures 40 are provided, and two placement grooves 102 are provided. The two pressing bodies 50 corresponding to the two placement grooves 102 are integrally provided. With this setting, the installation of the opposite ends of the two blade structures 40 can be achieved through one pressing structure, with a simple structure and convenient installation.

[0093] It should be noted that the two pressing bodies 50 can be integrally formed, that is, through integral injection molding. The two pressing bodies 50 are both connected to the grille frame 10 through a threaded connection structure or a snap connection structure.

[0094] In the embodiment where the other end of the blade structure 40 adopts an insertion method with shaft-hole fit, please refer to Figure 8 , a rotation connection hole 103 extending in the left-right direction is provided on the grille frame 10. One of the rotation shafts 2 is rotatably installed in the rotation connection hole 103. During installation, only by inserting the rotation shaft 2 into the rotation connection hole 103, the installation of the other end of the blade structure 40 and the grille frame 10 can be achieved.

[0095] Combined with the above embodiment of providing the placement groove 102 on the grille frame 10, when the operator installs the blade structure 40 on the grille frame 10, one of the rotation shafts 2 needs to be inserted into the rotation connection hole 103 first, and then the other rotation shaft 2 is placed in the placement groove 102. Preferably, the pressing body 50 is installed to achieve the installation of the blade structure 40, and the installation process is very simple.

[0096] The present utility model also proposes a vehicle front end assembly. The vehicle front end assembly includes an intake grille module 100. The specific structure of the intake grille module 100 refers to the above embodiments. Since the vehicle front end assembly adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.
